Heart Disease clinical trials at UCSD

The goal of this clinical trial is to learn how well and at what doses gadopiclenol, a new intravenous (IV) contrast agent used for MRI, works to produce high-quality MRI images of the heart, in patients with a history of congenital heart disease, when compared to gadobenate dimeglumine, the IV contrast agent that is normally used at our institution for heart (cardiac) MRI. The main questions it aims to answer are: - Does using gadopiclenol result in similar or superior image quality, similar signal-to-noise ratio (SNR), and similar flow measurements with 4-dimensional (4D) flow cardiac MRI when compared to gadobenate dimeglumine? - At what dose(s) does gadopiclenol result in similar image quality (using the above metrics) for cardiac MRI when compared to gadobenate dimeglumine? Researchers will compare cardiac MRI images obtained after administration of gadopiclenol to cardiac MRI images obtained after administration of gadobenate dimeglumine (called the standard of care treatment) to see if the images are of similar or superior quality. Participants will: - Be randomized to receive either gadopiclenol at one of three different doses or gadobenate dimeglumine before their congenital heart cardiac MRI - Undergo their congenital heart cardiac MRI as they would during the course of normal clinical care.

This trial will evaluate Orbital Atherectomy compared to conventional balloon angioplasty technique for the treatment of severely calcified lesions prior to implantation of drug-eluting stents (DES).

This study will look at the effects of providing medically tailored meals (MTMs) to people with heart disease for twelve weeks. The primary outcome of the study is the quality of the diet being consumed in week 12 of the study, as determined by the "Healthy Eating Index."

The purpose of this study is to see if reducing the number of hours during which one eats each day will help reduce levels of LDL cholesterol and improve other markers of metabolic and cardiovascular health (i.e. blood sugar levels and blood pressure). The study also aims to assess changes in exercise capacity and trimethylamine N-oxide (TMAO) levels in response to Time Restricted Eating (TRE) and Intensive Cardiac Rehabilitation (ICR) versus ICR alone. TMAO is a metabolite, or a substance, produced during digestion and metabolism. Preliminary data illustrates a correlation between high levels of TMAO and higher risk of cardiovascular disease and mortality. We will also be looking at participants' long-term cardiovascular health status after they complete the ICR program.

The objective of this study is to assess the safety and initial effectiveness of the TIVUS™ System when used for pulmonary artery denervation in group II PH patients through change in clinical parameters including hemodynamics, exercise tolerance, and quality of life. This is a prospective, multi-center, non-randomized, open-label clinical trail. The study will be conducted in up to 3 centers and will recruit up to 15 patients diagnosed with pulmonary hypertension due to left heart disease that demonstrate combined pre and post capillary involvement with PVR>3 wood units.

This retrospective study will evaluate the coronary angiograms of approximately 100 patients who have undergone invasive angiography and fractional flow reserve (FFR). DICOM files of the angiograms will be analyzed on a secure computer within the cardiac catheterization laboratory using the AutocathFFR software to assess if invasive FFR measurements and automated computer analysis of FFR measurements correlate. AutocathFFR measurement per lesion will be compared to the gold standard, invasive FFR value, where an FFR ≤ 0.80 will be considered "positive", while an FFR > 0.8 will be considered "negative". The AutocathFFR value will be compared to the invasive FFR measurements. The sensitivity and specificity of the AutocathFFR will be calculated, as well as the AutocathFFR accuracy, positive predictive value and negative predictive value per lesion. Device success will be calculated as the ratio of completed versus initiated AutocathFFR index calculations. Usability of the AutocathFFR software will be evaluated using dedicated questionnaires to be completed by the user (cardiologists).
